Abstract
The disclosure relates generally to a broadband antenna element with a reflecting cavity, which includes a metal frame, a feeder line, a feed screw, a pillar and an insulating sleeve. The reflecting cavity is formed by the inner concave of the outer side of the metal frame. The reflecting cavity includes the first wall and the second wall distributed from bottom to top. The first wall, the pillar, the second wall and the feeder line are arranged orderly and are connected with the feed screw. The pillar and the feed screw are connected by screw thread. The feed screw is connected with the second wall through an insulating sleeve. The pillar is a good conductor and under surface of the pillar contacts with the first wall, and the under surface area of the pillar is larger than the upper surface area of the pillar.
